Elastic sealing membrane DN125

Elastic sealing membrane for hermetic sealing of the hole between the pipeline (plastic, cast iron, stainless steel) d 125-130 mm and building structures (outer walls of the basements). Multi-tongue gasket with bitumen collar made of high-quality material and with a plastic safety nut for a firm hold. Easy to put on a smooth end of a pipe or socket, easy to install on uneven surfaces or in the corners of a building (thanks to a special design). Tested for water tightness (up to 6 m water column) - pipe axis deviation is allowed up to 10% from the mounting hole axis.
